Hey Guys,
I just have a quick question which stems from alot of the advice and discussions which I am commonly reading through. Specifically a "Cheaper" oil and a "Top Tier" oil both being excellent choices for ordinary passenger vehicles (...?)
Im just going to use for Example, Chevron Supreme Motor oil (commonly in the $12-$14 for 5 quarts) and Mobil 1 (commonly in the $22 - $30 for 5 quarts). My question is: How can both of these oils be recommended and praised as excellent oils when one is conventional, not specifically formulated for extreme or extended use. Is it because the users are typically not trying to over use the oil with an extended OCI or are we strictly looking at TBN to weigh the "Quality" of the oil?
The different interval you use each of the oils.
Uhh,
They both meet Ford spec, so
If a N/A Fiesta or Focus recommends 10k ocis, theyll ideally both go 10k mi, because ford has approved it.
I'm sure mobil 1 could probably further, but a car under warranty, extended oil changes can be considered "neglectful maintenance" in the eyes of the OEM who says 10k and no more.
Under warranty, any oil that meets the OEM spec and is API certified should be able to cover the recommended oci. After the warranty is up, extend all you want, but for warranty purposes on a vehicle such as a Ford, where both oils meet spec, Mobil 1 is equal to Supreme and any other Ford specced oil
